In this study, 300 raw buffalo, cow and ewe milk samples from five townships in west Azerbaijan, Iran, were analysed. Lead and cadmium were determined using atomic absorption spectrophotometry. Mean concentration of lead and cadmium in buffalo milk samples was 0.018 ± 0.001 and 0.003 ± 0.001 mg/kg, respectively. Mean concentration of lead and cadmium in cow(More)
The presence of toxic metals in milk may create significant health problems for the population. In this study, 1440 raw cow and ewe milk samples from 18 townships in north-east Iran were analysed in four different seasons. Lead, cadmium and mercury levels were determined using atomic absorption spectrophotometry. Mean concentration of lead, cadmium and(More)
OBJECTIVE To estimate the prevalence and distribution of bluetongue virus antibody in sheep and goats in 25 townships of Khorasan Razavi. Bluetongue is an infectious, non-contagious, arthropod born viral disease of ruminants and has been reported from most of the tropical and subtropical regions of the world. METHODS A total number of 1 034 serum samples(More)
Lead poisoning remains a serious problem in veterinary and human medicine. A number of lead chelators have been used for treatment of lead intoxication, but none of them is completely effective to remove lead from all organs. Therefore, alternatives for the treatment of lead poisoning are required. In this study, the efficacy of thiamine on blood and tissue(More)
It has been shown that garlic and its main bioactive component, allicin, as natural chelating agents can reduce blood and tissue lead content in animal models. In this study the effect of allicin, alone or combined with meso-2,3-dimercaptosuccinic acid (DMSA), in decreasing lead content of blood and tissues of mice was evaluated. Swiss albino mice were(More)
Glycyrrhiza glabra L. is used in folk medicine for treatment of stomach disorders including peptic ulcers. The hydroalcoholic extract of Glycyrrhiza glabra L. (HEGG) was evaluated for antiulcerogenic activity and acute toxicity profile in mice. Various doses of HEGG (50-200 mg/kg) were administered orally to animals of different groups. Omeprazole and(More)
Cadmium is a well recognized environmental pollutant with diverse toxicity in various organs of human and animals (IARC, 1993). Prolong cadmium exposures can cause lung fibrosis, kidney tubular dysfunction, hypertension, osteoporosis, cancer, etc. (Peters et al., 1986; Patra et al., 2011). The common sources of cadmium are combustion of coal, mining,(More)
Blood transfusion is an important remedy to manage animals with severe anemia. The risk of pathogen transmission can be reduced using autologous blood transfusion. Due to the lack of studies related to the use of autologous blood transfusions in goats, this study was conducted to evaluate the clinical, hematological, and biochemical changes following blood(More)
Previous experimental results have revealed that garlic (Alium sativum) can reduce lead toxicity and tissue lead content in lead-exposed rodents. In the present study, the effects of different doses of allicin, the main active constituent of garlic, in reducing of organ and blood lead levels were evaluated in mice exposed to 1,000 ppm of lead acetate in(More)
An outbreak of acute oxalate intoxication in a sheep flock was associated to Seidlitzia rosmarinus (Chenopodiaceae) with a mortality rate of about 19%. Affected sheep showed marked azotemia and hypocalcemia. Post-mortem findings included congestion and hemorrhage in visceral organs, ruminitis frequently associated with precipitation of birefringent calcium(More)
